Originální abstrakt

Paper presents a study focused on the evaluation of accuracy of polynomial shape functions utilized for description of the stress and deformation fields in cracked body and determined from solution of these fields using numerical tools, mainly using finite element method. The accuracy is quantified with regard to use in specimens made from quasi-brittle material characterized by large nonlinear zone at the crack tip. The analysis is performed as a reverse reconstruction of stress field in a cracked body and one suitable variant (which fulfills the required accuracy) is chosen
